Abstract:
A surgical tissue retractor for use in small tissue incisions such as heart valve surgery. The retractor is comprised of a plurality of retractor blades that can be operated simultaneously or at least one or more blades can be operated independently. Right and left retractor blades are mounted on an actuator mechanism that spreads or expands the blades as a rotatable primary actuator knob is rotated. A third retractable arm is mounted for simultaneous operation with the right and left retractor blade or independent operation through a secondary rotatable actuator knob that extends or retracts a threaded shaft attached to the center retractor blade. The retractor includes a housing having a hangar for use of the retractor in conjunction with a larger retractor such as a sternum spreader or rib spreader retractor.
